I've owned this little bug light/lantern for several months now. It does work on small, flying insects. I didn't have mosquitoes but I did have gnats & those tiny fruit flies that come in with the produce you buy. I can attest that it does kill them & it does it silently. No zapping noises. That's a big plus to me. The fact that it has a rechargeable battery is another big plus. No batteries to change out. It also comes with the charging cord & a small cleaning brush. It doesn't come with a charger though. That wasn't a problem for me because I have several that I can use to charge this little light. Oh, and the two level light is nice too. One is very dim, something akin to a nightlight & the other setting is brighter. All in all I like this item & I'm pleased with this purchase.
